Docker Queue & Horizon Setup
This directory bundles ready-to-use entrypoint scripts and deployment notes for running Fotospiel’s queue workers inside Docker containers. The examples assume you already run the main application in Docker (e.g. via docker-compose.yml) and share the same application image for workers.
1. Prepare the application image
Make sure the worker scripts are copied into the image and marked as executable:
# Dockerfile
COPY docs/queue-supervisor /var/www/html/docs/queue-supervisor
RUN chmod +x /var/www/html/docs/queue-supervisor/*.sh
If you keep the project root mounted as a volume during development the chmod step can be skipped because the files will inherit host permissions.
2. Queue worker containers
Add one or more worker services to docker-compose.yml. The production compose file in the repo already defines queue and media-storage-worker services that call these scripts; the snippet below shows the essential pattern if you need to tweak scaling.
services:
queue-worker:
image: fotospiel-app # reuse the main app image
restart: unless-stopped
depends_on:
- redis # or your queue backend
environment:
APP_ENV: ${APP_ENV:-production}
QUEUE_CONNECTION: redis
QUEUE_TRIES: 3 # optional overrides
QUEUE_SLEEP: 3
command: >
/var/www/html/docs/queue-supervisor/queue-worker.sh default
media-storage-worker:
image: fotospiel-app
restart: unless-stopped
depends_on:
- redis
environment:
APP_ENV: ${APP_ENV:-production}
QUEUE_CONNECTION: redis
QUEUE_TRIES: 5
QUEUE_SLEEP: 5
command: >
/var/www/html/docs/queue-supervisor/queue-worker.sh media-storage
media-security-worker:
image: fotospiel-app
restart: unless-stopped
depends_on:
- redis
environment:
APP_ENV: ${APP_ENV:-production}
QUEUE_CONNECTION: redis
QUEUE_TRIES: 3
QUEUE_SLEEP: 5
command: >
/var/www/html/docs/queue-supervisor/queue-worker.sh media-security
Scale workers by increasing deploy.replicas (Swarm) or adding scale counts (Compose v2).
Heads-up: Guest push notifications are dispatched on the
notificationsqueue. Either add that queue to the default worker (queue-worker.sh default,notifications) or create a dedicated worker so push jobs are consumed even when other queues are busy.
3. Optional: Horizon container
If you prefer Horizon’s dashboard and auto-balancing, add another service:
services:
horizon:
image: fotospiel-app
restart: unless-stopped
depends_on:
- redis
environment:
APP_ENV: ${APP_ENV:-production}
QUEUE_CONNECTION: redis
command: >
/var/www/html/docs/queue-supervisor/horizon.sh
Expose Horizon via your web proxy and protect it with authentication (the app already guards /horizon behind the super admin panel login if configured).
4. Environment variables
QUEUE_CONNECTION— should match the driver configured in.env(redisrecommended).QUEUE_TRIES,QUEUE_SLEEP,QUEUE_TIMEOUT,QUEUE_MAX_TIME— optional tuning knobs consumed byqueue-worker.sh.STORAGE_ALERT_EMAIL— enables upload failure notifications introduced in the new storage pipeline.SECURITY_SCAN_QUEUE— overrides the queue name for the photo antivirus/EXIF worker (media-securityby default).- Redis / database credentials must be available in the worker containers exactly like the web container.
5. Bootstrapping reminder
Before starting workers on a new environment:
php artisan migrate
php artisan db:seed --class=MediaStorageTargetSeeder
Existing assets should be backfilled into event_media_assets with a one-off artisan command before enabling automatic archival jobs.
6. Monitoring & logs
- Containers log to STDOUT; aggregate via
docker logsor a centralized stack. - Horizon users can inspect
/horizonfor queue lengths and failed jobs. - With plain workers run
php artisan queue:failed(inside the container) to inspect failures andphp artisan queue:retry allafter resolving issues.
7. Rolling updates
When deploying new code:
- Build and push updated app image.
- Run migrations & seeders.
- Recreate worker/horizon containers:
docker compose up -d --force-recreate queue-worker media-storage-worker horizon. - Tail logs to confirm workers boot cleanly and start consuming jobs.
8. Running inside Dokploy
If you host Fotospiel on Dokploy:
- Create separate Dokploy applications for each worker type using the same image and command snippets above (
queue-worker.sh default,media-storage, etc.). - Attach the same environment variables and storage volumes defined for the main app.
- Use Dokploy’s one-off command feature to run migrations or
queue:retry. - Expose the Horizon service through the Dokploy HTTP proxy (or keep it internal and access via SSH tunnel).
- Enable health checks so Dokploy restarts workers automatically if they exit unexpectedly.
These services can be observed, redeployed, or reloaded from Dokploy’s dashboard and from the SuperAdmin integration powered by the Dokploy API.
